Change Launchpad’s Background Image Effect in Mac OS X Lion

Bored with Launchpads background? You can make some changes to it in Mac OS X Lion by changing the background images default blur effect to three other options: unblurred (shown above), black and white blur, or black and white unblurred (both shown below):

Open Launchpad

Hit Command+B to cycle through the background image effects

Update: In OS X 10.7.3, you need to use Command+Control+Option+B to achieve the same effect

Hitting Command+B once should just remove the blur from the background image, which makes Launchpad more closely resemble the iOS springboard. You can use the keystroke a few more times to switch into black and white or to go back to the default blur.
